electro-magnet definition

  • noun:
    • a size, generally of smooth iron, but sometimes of other magnetic material, as nickel or cobalt, rendered briefly magnetic by being placed within a coil of line whereby a current of electricity is driving. The steel is typically in the shape of a bar, either straight, or bent into the form of a horseshoe.
    • A magnet which owes its magnetic properties into inductive action of an electric powered current.
    • If an insulated cable is wound about a bar of soft metal and a current of electrical energy is passed through it, the bar becomes a temporary magnet with a north and a south pole; the finish where the present circulates through cable toward the arms of a-clock, while the observer looks at it, may be the south pole. In practice, an electromagnet features normally a horseshoe form. It is made from two cylinders, or cores, of soft iron, fastened collectively at one end and each wound many times with insulated cable; the line must certanly be so wound that when the horseshoe were straightened the way of winding is the same throughout. An electromagnet can be made very powerful, so as to support a ton or maybe more. The smooth iron core retains its optimum magnetization only provided that the existing is moving, and manages to lose the majority of from it the minute the existing ceases. This concept is made usage of when you look at the telegraph (which see), electric clocks, electric callbells, etc. If the core is constructed of metal, it becomes underneath the activity of present a permanent magnet.
    • a short-term magnet made by coiling cable around an iron core; when present flows in coil the iron becomes a magnet
    • A mass, typically of soft iron, but sometimes of other magnetized material, as nickel or cobalt, rendered briefly magnetized by being put within a coil of line through which a current of electrical energy is passing. The material is usually in the form of a bar, either straight, or bent in to the shape of a horseshoe.
    • A magnet which owes its magnetic properties into inductive action of a power present.
    • If an insulated cable is wound about a bar of smooth metal and a present of electrical energy is passed through it, the club becomes a temporary magnet with a north and a south pole; the end at which the current circulates through cable in the direction of the fingers of a-clock, once the observer looks at it, is the south pole. Used, an electromagnet has normally a horseshoe kind. It comes with two cylinders, or cores, of smooth iron, fastened collectively at one end and every wound many times with insulated cable; the cable must certanly be so wound that if the horseshoe had been straightened the path of winding would be the same throughout. An electromagnet are made extremely effective, to be able to help a lot or higher. The smooth iron core keeps its optimum magnetization only as long as the present is moving, and manages to lose most of it the instant the current ceases. This concept is made usage of within the telegraph (which see), electric clocks, electric callbells, etc. If the core is constructed of metal, it becomes underneath the action associated with the existing a permanent magnet.
    • a short-term magnet produced by coiling wire around an iron core; whenever current flows inside coil the iron becomes a magnet
    • A mass, frequently of soft iron, but occasionally of several other magnetized material, as nickel or cobalt, rendered briefly magnetic when you are put within a coil of line by which a current of electricity is passing. The steel is generally in the shape of a bar, either straight, or bent in to the form of a horseshoe.
    • A magnet which owes its magnetic properties toward inductive action of a power up-to-date.
    • If an insulated wire is wound about a bar of smooth metal and a current of electricity is passed through it, the bar becomes a short-term magnet with a north and a-south pole; the finish of which current circulates through cable toward the hands of a-clock, because the observer looks at it, may be the south pole. Used, an electromagnet features normally a horseshoe form. It contains two cylinders, or cores, of smooth metal, fastened together at one end and each wound several times with insulated cable; the line must certanly be therefore wound that if the horseshoe were straightened the course of winding is the exact same throughout. An electromagnet might be made very powerful, so as to support a ton or even more. The soft iron-core keeps its optimum magnetization just as long as the existing is passing, and manages to lose almost all from it the instant the existing ceases. This principle is created utilization of inside telegraph (which see), electric clocks, electric callbells, etc. In the event that core is made of metallic, it becomes in action for the existing a permanent magnet.
    • a temporary magnet created by coiling cable around an iron core; when current flows into the coil the metal becomes a magnet
